The CW Developing 'Vampire Diaries' Spin-Off 'The Originals'

A backdoor pilot for the potential new show about the Original family led by Klaus will air April 25.

A spin-off to "The Vampire Diaries" is officially in the works with The CW planning to introduce the potential new series through a backdoor pilot. The project currently called "The Originals" revolves around the original family of vampires with Joseph Morgan's Klaus as the main character.

The pilot for the potential new series will air as a "TVD" episode scheduled for April 25. In it, Klaus "returns to the supernatural melting pot that is the French Quarter of New Orleans - a town he helped build centuries ago - and is reunited with his diabolical former protege Marcel." Phoebe Tonkin will reprise her role as werewolf Hayley in the said outing.

The Originals led by Klaus first appeared on "TVD" in season 2 and have become major part of the storyline. If the spin-off gets a series order, "TVD" executive producer Julie Plec will serve as the showrunner.
